BlockLauncher's build system is complicated and out of date. It still uses Ant (and thus is incompatible with Android Studio), and uses older versions of various libraries.
Scripts to setup a build environment can be found in tools/ci/ci_build.sh.
This script is tested to work on GitHub Actions' Ubuntu 18.04 image, and on a fresh Ubuntu 19.10 install.
You may need to install:
sudo apt install git p7zip-full openjdk-8-jdk ant
sudo update-java-alternatives -s java-1.8.0-openjdk-amd64
